In order to study the effect of lead exposure on the hematocrit and hemoglobin values in accordance with the level of lead exposure, twenty-four Sprague-Dawley rats were equally divided into four groups of six rats each. Lead acetate disolved in glucose was injected intraperitoneally six times a week, for four weeks with dose of 0.05 mg/kg/day for group I, 0.5 mg/kg/day for group II, and 5 mg/kg/day for group III. Control group was injected glucose only. Blood samples for the checking of the hematocrit and hemoglobin values, were taking from tail vein of rats before lead injection and on the third, seventh, fourteenth, twenty-first, and twenty-eighth days after lead injection. And also, the concentration of lead and ALA in urine were checked for evaluating the lead absorption. The results were as follows: 1. The alteration of the hematocrit and hemoglobin values of the group I was not significant as that of the control group. 2. In group II, the hematocrit values were significantly decreased from the fourteenth day after lead injection, and the hemoglobin values were decreased from the twenty-first day after lead injection when the concentration of lead in urine was elevated more than $260{\mu}g/liter$. 3. In group III, the hematocrit values were decreased from the seventh day after lead injection, and the hemoglobin values were decreased even from the third day after lead injection. And the hemoglobin values were more rapidly decreased than the hematocrit values. 4. In all groups, the correlation coefficient between hematocrit and hemoglobin was highly significant. And the difference between the correlation coefficient of the group III and that of the others was highly significant.

This study aims to show how tradition and modernity has interacted to produce the aesthetic consciousness of body and dress in contemporary Korea. For this purpose, documentary studies were proceeded. And photos of the modern Korean dress from 1980 to 1997 were analyzed. The results are as follows: First, the body form was studied in terms of exposure and concealment of the physical body parts and the perception of body was classified into two categories, the abstract and the realistic. And the dress form was studied in silhouette and the perception of dress was assorted as body priority and clothes priority. Second, the aesthetic values of body were categorized to divinity, humanity and sexuality. And the aesthetic values of dress were defined in relation to the aesthetic values of body as ascetic beauty, pure beauty, natural beauty and erotic beauty. Third, while the traditional Korean costume (Hanbok) pursues the aesthetic values of divinity and humanity of human body and ascetic beauty, pure beauty and natural beauty on the aesthetic values of humanity of human body and the pure beauty and natural beauty of dress. The contemporary Korean fashion expresses the aesthetic values of divinity, humanity and sexuality of human body and the aesthetic values of ascetic beauty, pure beauty, natural beauty and erotic beauty of dress. In conclusion, the emphasis of sexuality of body and erotic beauty of dress in the modern Korean dress can be interpreted as the change of the aesthetic consciousness of body and dress in contemporary Korean by the influence of the western modernity.

The purpose of this study was to investigate the ethical values of senior students in nursing (N＝111) and in medicine(N＝82). The data were collected through self-reported questionnaires in April, 1999. Categories for classifying used in the content analysis of the responses were : (1) human life (2) patient relationship (3) task relationship and (4) co-worker relationship. The results of the study are as follows ; 1) The ethical values of students in nursing and medicine were in the direction of utilitarian in the area of human life. The ethical values of students in nursing and medicine were in the direction of a deontological position in the area of patient relationship. The mean score for students in nursing was significantly higher than for those in medicine(P＜0.01) The ethical values of students in nursing and medicine was in the direction of utilitarian in the area of task relationship. The mean score for students in medicine was significantly lower than that of students in nursing(P＜0.01). The ethical values of students in nursing and medicine was definitely in the direction of a deontological position in co-worker. The mean score for students in nursing was significantly higher than that of students medicine (P＜0.05). 2) A positive correlation was found between the area of human life and patient relationship(P＜0.05), patient and task relationship(P＜0.01), and task and co-worker relationship(P＜0.05) for students in nursing. On the other hand, the area of human life was positively correlated with patient, task and co-worker relationship area(P＜0.05) for students in medicine. The area of patient relationship was also positively correlated with co -worker relationship for the students in medicine(P＜0.01). 3) The ethical values of students in nursing were related to demographic characteristics ; degree of participation in religion(P＜0.01)and degree of recognition of an ethical codes(P＜0.05), on the other hand, the ethical values of students in medicine showed no significant differences according to demogrephic variables.

This study was conducted to develop the mathmatical model for predicting the side thrust which is generated by the shearing action on the vertical surfaces of the sides of the track. Experiments were conducted with the three different shear plates with grouser length of 1, 3 and 5 cm for two different soil condition using soil bin system. The measured side thrust were compared with the values predicted by the new model developed in this study and by Bekker's model respectively. The values of side thrust predicted by the new model were more close to the measured values than those of the side thrust predicted by Bekker's model . The total thrust measured were also compared with the values predicted by the conventional model which considers only bottom thrust effect and by the new model which contains not only bottom thurst but side thrust effect. The values of the thrust predicted by conventional modelwere lower than measured values for both of the soil conditions and the three levels of grouser length. The maximum errors of conventional model were increased with the increase of grouser length. but the values of the total thrust predicted by the model developed in this study were well matched to the measured ones for both of the soil conditions and the three levels of grouser lengths.

This study aims to examine the effects of talent types and appearance affect perception on the clothing consumption values in 367 adults(female and male). The present study is the first to consider both talent types and the appearance affect perception on the clothing consumption values correlates to appearance management behaviour. As a results, the talent type of 367 respondents was mean=3.324. The highest talent of 367 respondents was interpersonal talent, the lowest talent was logical-mathematical talent among 8 talent types. The effects of 8 talent types on 5 clothing consumption values were significant on the regression analysis, specifically the results showed that the effects of linguistic, musical, interpersonal and intrapersonal talents among 8 talent factors on the clothing consumption value were significant. Regression results showed that if the practical and the inner-directed appearance affect perception factors among 3 appearance affect perception factors increase by one standard deviation, the social, political, aesthetic, and emotional clothing consumption values increase by each standardized efficient ${\beta}$. The effects of 8 demographic factors on 5 clothing consumption values were significant on the regression analysis, specially, occupation, monthly clothing allowance, income, and sex variables were significant, the results revealed that if the occupation factor(specialist and administrator) increases by one standard deviation, the social, political, aesthetic, and emotional clothing consumption values increase by each standardized efficient ${\beta}$. Finally, this study suggests that the 3 independent variables(talent types, appearance affect perception factors, and demographic factors) were predictors related to clothing consumption values. The higher the score, it was concluded that the independent variables were more active in clothing consumption behaviour.

In this paper, we analyzed the operation of the ignition circuit for electronic arm and fire device(EAFD), and investigated the sensitive elements of the circuit system. For reliability analysis, the EAFD ignition circuit was modeled using the PSpice simulation tool, and the output results of the circuit were examined by changing the tolerance of each circuit element. Monte Carlo simulation was used by maintaining the values of the observed sensitive elements at ${\pm}10%$ of the original values and adjusting the values of the other components according to a random distribution. The histogram results of the output peak currents and pulse widths were represented by Weibull and Burr type XII function fittings in three cases(element values are +10 %, 0 %, -10 % of original). For the output peak currents, mean values were 1.0028, 1.0034, and 1.0050, where the variance values were calculated as 0.0398, 0.0396, and 0.0290 using the Weibull function fitting, respectively. For pulse widths, the mean values of 0.9475, 0.9907, and 1.0293 with the variance values of 0.0260, 0.0251, and 0.0238 were obtained using the Burr Type XII function fittings.

This study suggests a method to predict the color appearance of textiles that shifts depending on illumination variations. The suggested method allows the calculations of lightness, chroma, and hue appearance values from the spectral reflectance values of the textile and illuminant. The accuracy of the method was evaluated through numerical and statistical comparisons between the predicted and the measured color appearance values of 24 fabric samples under CIE standard illuminant D65. As a result, there were excellent agreements between the two data sets with the error values close to zero. The predicted color appearance values of 24 samples under two illuminating (color temperature-luminance) conditions, 2700 K-100 cd/㎡ and 6500 K-100 cd/㎡, were then compared to prove the significant effect of illumination on the color appearance of textiles. The color appearance values were also compared with spectrophotometrically measured physical color attributes, that is, true colors of the samples. The physical color attributes of samples were unchanged; however, differences in color appearance under different conditions were generally much larger than the suprathreshold color difference tolerances discussed in the color science literature. Finally, the magnitude of the illumination effect depending on the physical color attributes of samples was also analyzed.

The purpose of this study is to determine values and value changes of the four year course nursing college students. The survey was conducted against 262 students of the nursing college, from all classes (freshman, sophomre, junior and senior). This study was conducted during the period of first through 15th of December 1984 in accordance with the L.V. Gordon's“Survey of Interpersonal Values (SIV)”. The results of the study were as follows: 1. Those nursing students surveyed show that conformity (16.32) took the highest place and reconition (10.21) lowest in the general value orientation. In accordance with the Cordon's SIV, those of other woman college students indicate 14%ile-65%ile, respectively. 2. Changes in values by class indicate that freshman, sohpomore and senior students showed similar Pattern but junior students showed significantly lower than other classes. The difference should be considered on the basis of statistics (p <.05). Accordingly, the hypho-thesis 1 of this study has been supported. 3. Significant variation has been shown by each class in each factor such as support, conformity, independence and benevolence but no variation has been indicated in leadership and recognition. 4. There was difference in values between higher class (jounior and senior) students with clinical experience and starting class (freshman and sophomore) students without clinical experience. The study indicates the values of higher class. students is lower than that of starting class. students (P <.05). Therefor, the hyphothesis 2 of this study has been supported. 5. There was no significant difference in values between entering students and graduating students (p<.05), Thus, the hyphothesis 3 of this study has been rejected. The results of the finding of the study show that there is no positive influence in forming the values. for the students. Therefore, it is concluded that new strategy and special educational program should be established for formulation of the right values for the nursing college students.

Objectives: The objective of this study was to develop a zinc database (DB) to estimate the intake levels of zinc in Korean toddlers and preschool children using the data from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 3,361 food items for the DB representing the usual diet of Korean toddlers and preschool children were selected based on KNHANES (2009~2013) and the food composition table of Rural Development Administration (RDA). The existing values of zinc in foods were collected from the latest food composition tables of RDA (9th revision) and the US Department of Agriculture (legacy release). The zinc contents were filled preferentially with these collected values. The missing values were replaced with the calculated values or imputed values using the existing values of similar food items from the data source. The zinc intake levels of Korean toddlers and preschool children were estimated using KNHANES and zinc DB Results: A total of 1,188 existing values, 412 calculated values, and 1,727 imputed values were included in the zinc DB. The mean intake levels of zinc for 1-2-year-old children and 3-5-year-olds were 5.17 ± 2.94 mg/day and 6.30 ± 2.84 mg/day, respectively. There was no significant difference in the zinc intake levels between boys and girls in each group. Conclusions: This newly developed zinc DB would be helpful to assess the zinc nutritional status and investigate the association between the zinc intakes and related health concerns in Korean toddlers and preschool children.

Multi-temporal satellite imagery can be changed into a transform image that emphasizes the changed area only through the application of various change detection techniques. From the transform image, an automated change detection model calculates the optimal threshold value for classifying the changed and unchanged areas. However, the model can cause undesirable results when the histogram of the transform image is unbalanced. This is because the model uses a single threshold value in which the sign is either positive or negative and its value is constant (e.g. -1, 1), regardless of the imbalance between changed pixels. This paper proposes an advanced method that can improve accuracy by applying separate threshold values according to the increased or decreased range of the changed pixels. It applies multiple threshold values based on the cumulative producer's and user's accuracies in the automated binary change detection model, and the analyst can automatically extract more accurate optimal threshold values. Multi-temporal IKONOS satellite imagery for the Daejeon area was used to test the proposed method. A total of 16 transformation results were applied to the two study sites, and optimal threshold values were determined using accuracy assessment curves. The experiment showed that the accuracy of most transform images is improved by applying multiple threshold values. The proposed method is expected to be used in various study fields, such as detection of illegal urban building, detection of the damaged area in a disaster, etc.
